    Abstract: A passive arrayed-waveguide-grating (AWG) router that can be used to implement the dual functionality of a wavelength router and a 3-dB power splitter for one of its wavelength channels while functioning as a conventional wavelength router for the other wavelength channels. The passive AWG router can advantageously be used, e.g., in a WDM-PON system to reduce the insertion-loss disparity between the various wavelength channels that are being used to broadcast optical signals from an optical line terminal located at the service provider's central office, through the passive AWG router, to a plurality of optical network units located near the end users.

    Abstract: A wavelength-selective cross-connect (WSXC) device configured to route any set of carrier wavelengths from a corresponding input port to any selected output port. The WSXC device comprises a diffraction grating and a beam-steering device optically coupled to one another and to the input/output ports using astigmatic optics. The astigmatic optics includes one or more cylindrical lenses configured to image one beam-steering surface onto another beam-steering surface to enable a continuous spectral response. The astigmatic optics may further include (i) a cylindrical Fourier lens that enables the WSXC device to convert a change in the angular beam steering performed by the beam-steering device into a corresponding image-spot displacement at the output ports and/or (ii) one or more cylindrical lenses configured to image the active surface of the beam-steering device onto the diffraction grating. Various unfolded configurations of the various embodiments of the WSXC device are also disclosed.

    Abstract: A WDM device having a controller that individually controls the operating parameters of tunable lasers and the temperatures of an optical multiplexer and etalon. The device employs a spectral analyzer to measure the spectral composition of the optical output signal produced by the device. Based on the analyses of the measured spectral composition, the controller sets the temperatures of the tunable lasers, optical multiplexer, and optical etalon to values that cause: (i) middle frequencies of transmission bands of the optical multiplexer to be spectrally aligned with the corresponding frequencies of the specified frequency grid, (ii) each laser line to be properly positioned within the corresponding transmission band, and (iii) transmission resonances of the optical etalon to be properly positioned with respect to the laser lines.

    Abstract: An optical-power-distribution (OPD) subsystem that provides means for supplying optical local-oscillator signals and optical-carrier signals to various optical line cards, without the need for each optical line card to have a corresponding individual laser source. In one embodiment, a single laser coupled to the OPD subsystem provides optical local-oscillator signals and optical-carrier signals to multiple optical line cards. In another embodiment, multiple lasers coupled to the OPD subsystem provide multiple optical local-oscillator signals and optical-carrier signals to a single line card. An OPD subsystem may provide significant power savings in the operation of the corresponding optical transport system, a reduction in the required equipment-cooling capacity, and an increase in the device-packing density within optical line cards and inside equipment cabinets that house optical line cards.

    Abstract: An optical transmitter that uses half-rate electrical signals, without multiplexing them to the full rate, to generate a full-rate optical duobinary signal. In one embodiment, an optical transmitter of the invention has a Mach-Zehnder modulator (MZM) driven by two half-rate electrical data streams. A first half-rate data stream is applied to drive a first arm of the MZM. A delay element misaligns a second half-rate data stream that is synchronized with the first data stream by one half of a bit period, and the resulting misaligned data stream is applied to drive a second arm of the MZM. The MZM is configured to (i) transmit substantially no light from the feeding laser when the applied data streams have the same binary value and (ii) have a maximum transmission when the applied data streams have different binary values, thereby generating a full-rate optical duobinary signal at its output.
